Specification of Letters Patent.

Patented April 2, 1907.

Application filed February 5, 1907. Serial No- 355,833.

To all wit/.2771 it may concern.-

Be it known that I, FRANK A. BORST, a citizen of the United States, and a resident of the city of South Bend, in the county of St. Joseph and State of Indiana, have invented a new and Improved Rockin Mechanism for Building Blocks and Bricks, of which the following is a specification.

My invention relates to means for transferring freshly-molded blocks or bricks from a plate which usually forms one of the sides of a mold and upon which the blocks or bricks are removed from the mold to another plate, upon which they may remain until the material has properly hardened.

My invention consists in a novel rocking mechanism for blocks and bricks which comprises a rocker formed of two portions at the proper angle to each other and two plates, one for carrying the molded blocks from the mold to the rocker and a second to carry the blocks from the rocker, the rocker proper being provided with a cross-bar which properly positions the plates.

In the accompanying drawings, Figure 1 is a perspective view of the rocker. Fig. 2 shows the rocking mechanism resting on one side with the plates in such position that the blocks rest on the first plate, the blocks being indicated in dotted lines. Fig. 3 shows the rocking mechanism after it has been turned to rest on the other side and with the blocks resting on the second plate. Figs. 4' and 5 show transverse sections of the mechanism with the parts in the positions shown in Figs. 2 and 3, respectively.

Similar reference characters refer to like parts throughout the several views.

In the drawings two side arms 1 of the rocker meet two other arms 2 at right angles, forming pairs. Cross-bars 3 and 4 connect the outer ends of the arms 1 and 2, respectively, and the cross-bar 5 extends across between the pairs of arms and lies within the angle formed by the arms 1 and 2.

In using this mechanism a plate 6 is employed for bringing the molded blocks or bricks 8 to the rocker and a plate 7 to carry them away. The plate 6 is generally one of the operative sides of a block or brick mold and is used with each block or batch of blocks or bricks. The plate 7 is any one of the usual large number of pallets that are to be found in any block factory and may be of any convenient thickness.

The angle between the arms 1 and 2 will depend upon the angle of the corner of the blocks, and the dimensions will depend upon the block-machine in connection with which this mechanism is to be employed.

The mechanism is operated as follows: The rocker being placed to lie on its arms 2, a storage-plate 7 is placed against the arms 1, its thickness being equal to the height of the bar 5, measured from these arms 1. The mold-plate 6, upon which the blocks 8 are carried from the mold, is then laid on the arms 2, one edge bearing against the crossbar 5 and its thickness equaling the height of this cross-bar measured from the arms 2. This should cause the block or bricks to contact with the plate 7 at both ends. The rocker is then turned from the position shown in Figs. 2 and 4 to that shown in Figs. 3 and 5, which will cause the blocks or bricks 8 to rest on the plate 7, upon which they may be carried to the storage-place to harden, the plate 6 being returned to the mold. If the plates are at the proper angle, so that there is no space between the blocks and the plate 7, these blocks may be turned without injury. The device is especially adapted for use with machines for molding concrete bricks, but is also useiul'in connection with block-molding machines where the blocks are removed from the machine on the plate which forms the face of the block.

Having now explained my construction,

-what I claim as my invention, and desire to secure by Letters Patent, is-

1. A rocking mechanism for building blocks and bricks comprising two side frames, each formed of arms, cross-bars connecting the frames, and plates adapted to carry the blocks and bricks.

2. A rocking mechanism for building blocks and bricks, comprising portions substantially at right angles to each other adapted to receive plates for carrying the blocks or bricks, and a rectangular bar extending across and within the angle between the two portions to properly position the plates.

3. A rocking mechanism for building In testimony whereof I have signed this blocks and bricks, comprising two side specification in the presence of two subscrib- 10 frames, each formed of arms at right angles ing Witnesses. to each other, cross-bars connecting the 5 outer ends of the arms, a third cross-bar lying Within the angle and connecting the inner Witnesses: ends of the arms, and plates adapted to carry GEO. B. HOPKINS, the blocks and bricks. CHAS. E. MOFFITT.
